We investigated whether ultrasound guidance was advantageous over the anatomical landmark technique when performed by inexperienced paediatricians.
Randomised controlled trial.
A paediatric intensive care unit of a teaching hospital.
80 children (aged 28 days to <14 years).
Internal jugular vein cannulation with ultrasound guidance in real time or the anatomical landmark technique.
Success rate, success rate on the first attempt, success rate within three attempts, puncture time, number of attempts required for success and occurrence of complications.
We found a higher success rate in the ultrasound guidance than in the control group (95% vs 61%, respectively; p<0.001; relative risk (RR)=0.64, 95% CI (CI) 0.50 to 0.83). Success on the first attempt was seen in 95% and 34% of venous punctures in the US guidance and control groups, respectively (p<0.001; RR=0.35, 95% CI 0.23 to 0.54). Fewer than three attempts were required to achieve success in 95% of patients in the US guidance group but only 44% in the control group (p<0.001; RR=0.46, 95% CI 0.32 to 0.66). Haematomas, inadvertent arterial punctures, the number of attempts and the puncture time were all significantly lower in the ultrasound guidance than in the control group (p<0.015 for all).
Critically ill children may benefit from the ultrasound guidance for internal jugular cannulation, even when the procedure is performed by operators with limited experience.

我们研究了在经验不足的儿科医生中,实时超声引导与解剖标志技术相比是否具有优势。
随机对照试验。
教学医院的儿科重症监护病房。
80 名儿童(年龄 28 天至<14 岁)。
实时超声引导下或解剖标志技术下进行颈内静脉置管。
成功率、首次尝试成功率、三次尝试内成功率、穿刺时间、成功所需尝试次数和并发症发生情况。
我们发现超声引导组的成功率高于对照组(分别为 95%和 61%;p<0.001;相对风险(RR)=0.64,95%置信区间(CI)为 0.50 至 0.83)。超声引导组 95%的静脉穿刺可首次成功,而对照组仅为 34%(p<0.001;RR=0.35,95%CI 0.23 至 0.54)。在超声引导组,95%的患者需要不到三次尝试即可成功,而对照组仅为 44%(p<0.001;RR=0.46,95%CI 0.32 至 0.66)。超声引导组血肿、意外动脉穿刺、尝试次数和穿刺时间均明显低于对照组(所有 p<0.015)。
即使由经验有限的操作者进行,超声引导可能有益于颈内静脉置管,尤其是在危重症儿童中。
